Binding energy & energy required to remove a nucleon

AI Thread Summary
The binding energy of the deuterium atom is 2.00 MeV, which is the total energy required to disassemble the nucleus into its individual nucleons. Removing a nucleon from deuterium requires supplying the full binding energy, not just half, because the nucleons will exist separately afterward. This explains why the energy required to remove a nucleon is 2.00 MeV rather than 1.00 MeV. The discussion clarifies that the binding energy must be fully supplied to achieve separation. Understanding binding energy is crucial for nuclear physics and reactions.

Homework Statement



lets's say the binding energy of 2_1 deuterium atom is 2.00MeV .. what's the energy required to remove a nucleon from the 2_1 deuterium atom

Homework Equations

The Attempt at a Solution

the ans is 2.00MeV...
why not 1.00MeV ??

because eneryg required to remove a nucleon is binding energy/ nucleon number (A) [/B]

Deuterium consists of one proton and one neutron. Removing a nucleon from the nucleus effectively leaves a disassembled nucleus, that is the two nucleons exist separately. That means that you have to supply the total binding energy to disassemble the nucleus into its two parts. They will then have their usual mass when they are separated.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
